The vulnerability CVE-2024-56298 in Pretty Simple Popup Builder (<=1.0.9) is a stored cross-site scripting issue caused by improper input neutralization during web page generation. This allows attackers with high privileges and requiring user interaction to inject malicious scripts that can impact confidentiality, integrity, and availability to a limited extent. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, and a scope change with partial impact on confidentiality, integrity, and availability.

Successful exploitation can lead to execution of arbitrary scripts in the context of affected users, potentially leading to data disclosure, modification, or disruption of service. The impact is limited by the requirement for high privileges and user interaction, and the overall severity is medium. There are no reports of active exploitation in the wild.
